Nano-particlesof a metal or the like are dispersed in a liquid fluid. Thereby, the reactivity or toxicity of the liquid fluid can be reduced when the liquid fluid has reactivity or toxicity. The flow resistance of the liquid fluid can be raised, and the leakage of the liquid fluid from minute cracks can be reduced. By using the liquid fluid as a heat transfer medium of a heat exchanger, the heat transfer performance equivalent to or higher than the heat transfer performance of the original heat exchanger can be obtained.

An electromagnetic flowmeter designed to use a smaller excitation device and applicable to measurement on tubular channels of various sectional shapes. The electromagnetic flowmeter includes an excitation device for forming a magnetic field perpendicular to an outer wall of a tubular channel, and a pair of electrodes for measuring an electromotive force generated by the movement of the electroconductive fluid across the magnetic field. The electrodes and two magnetic poles of the excitation device are collectively placed on the outer wall at one side of the tubular channel.
